enable FPU and implement up_fpucmp to pass ostest
With aggressive optimization enabled (-O2/-O3), ostest FPU test will fail.
This is because the compiler will generate additional vector
instructions between subsequent up_fpucmp() calls (loop vectorization
somewhere in usleep() call), which will consequently overwrite
the expected FPU context (XMM registers).

aggresive optimisation can replace occurrences of sinl() and cosl() with
sincosl(), but sincosl() is missing in newlib which causes error. So let's
use custom implementation here.

Currently at runtime it is hard to know the exact build config of
the current NuttX instance. Thus it is inconvenient when there are
multiple configs for the same board. This patch attempts to solve
the issue by adding build config to /proc/version.

fixes b4b96a6435 (PR #11758) in which the multiboot2 header was accessed
after revoking the low memory which caused page fault.

Define `NUTTX_DEFCONFIG` and `NUTTX_BOARD_ABS_DIR` instead of `BOARD_CONFIG`
when reconfiguring a custom configuration,
because ${BOARD_CONFIG} uses a relative path,
it will cause the following error:

DEBUG_FULLOPT enables many x86 related optimizations which can
be broken in many ways (eg. not aligned stack).
With this change it's easier to catch changes that breaks x86_64.

Align _ebss to 16, otherwise g_idle_topstack is not correctly aligned.
For some reason the previous alignment worked with make buit but in case
of cmake with optimization enabled, the IDLE stack was misaligned which
caused vector instruction misalignment exception.

The stack pointer must be aligned to 16 bytes, otherwise the system crash on the first unaligned data access with vector instruction.
The problem is only observable with optimization enabled, when vector instructions are generated.

During removal of F1 related stuff, code that configures FLASH
latency was removed, which rendered some of the F3 line unbootable.
It was done by mistake, since previous removed block was
'#ifdef VALUE_LINE', and block with FLASH code was '#ifndef VALUE_LINE'
and so it should not have been removed.

Add support for tricore TC397
1. Porting based on AURIX TC397 KIT_A2G_TC397_5V_TFT evaluation board
https://www.infineon.com/cms/en/product/evaluation-boards/kit_a2g_tc397_5v_tft/
2. In order to avoid license and coding style issues, The chip-level code
still uses the implementation of AURIX Development Studio SDK.
The SDK package will be downloaded as a third-party package during compilation:
https://github.com/anchao/tc397_sdk
3. Single core only, SMP implementation will be provided in the future.
4. Implemented the basic System Timer, ASCLIN UART driver.
5. Only the Tasking tool chain is supported (ctc/ltc, license maybe required)
6. 'ostest' can be completed on the TC397 development board.
How to run?
1. Setup the tasking toolchain and license
$ export TSK_LICENSE_KEY_SW160800=d22f-7473-ff5d-1b70
$ export TSK_LICENSE_SERVER=192.168.36.12:9090
2. Build nuttx ELF
$ ./tools/configure.sh tc397/nsh
$ make -j
...
artc I800: creating archive libc_fpu.a
LD: nuttx
3. Switch to windows PC, setup AURIX-studio to Debugger Launcher
4. Replace runing ELF to nuttx, and re-download ELF

In the previous patch, we moved rptun_panic and rptun_dump_all in rptun to rpmsg.
In order to ensure CI pass, this two API in rptun is not removed. So we remove rptun_panic and rptun_dump_all in this patch.

When we close a socket fd, it will call get path on sockets.
`close(socket_fd)` -> `file_closelk(filep)` -> `file_fcntl(F_GETPATH)`
It causes a heavy stack load for each socket close operation.
(We have `GETPATH` for sockets to be used for `fdinfo`)
But the socket fds are not intended to be used for file locks.
And so do some other file types, so we may just limit the usage of flock.
